MOTOR-PLOW.

To all whom it maconcern:

Be it known t at I, Nnw'ron F. CHAM- BERLIN, a citizen of the United States, residing at Libertyville, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Motor- Plows, of which the following is a specification.

This invention relates to .motor plows, and has for its object the production of a wheeled supporting carriage, triangular in arrangement, provided with a relativelylarge driving wheel having a peripheral construction adapted to follow the furrow and move a plow located before it. The guiding wheel on the carriage, and the side supporting wheel being so disposed as to always roll upon unplowed ground. with consequently even progress.

The object of this invention also comprises devices to be constructed and arranged for raising and lowering the plow, and means for securing the said devices upon the frame of the machine at different points toward or from the main driving or traction wheel.

In the accom anying drawings, Figure 1 represents a si'e view of several parts assembled, and Fig. 2 is a plan view complete, taken from above. Fig. 3 shows a portion of the main frame and certain bolt holes therein.

Throughout the drawings and specification the same letter is used to refer to the same part.

The main frame A, suitably braced and strengthened, is provided at its rear 'end with the platform B, extending at right angles with the main frame. At the forward end of the main frame A is a vertical post C, and to the post is secured the bearing D that serves to hold vertically and rowheel, the guide .wheel H is moved corre-.

spondingly and the carriage may be guided. It will be noted that the operators seat J is situated at one side of the main frame, and the hand wheel 9 is adjacent to it and within easy reach. It will also be observed Specification of Letters Patent.

that the motor K is arranged within reach of the seat J, both being borne by theplat form B. Thus,.the operator is enabled .to conveniently attend to the steerin gear and to the motor, yet need not leave his seat'to do so.

Near the rear end of the main frame A are located the bearings L for the driving wheel M. In practice it is advantageous to provide the periphery of the drive wheel M with the V-shaped blades m,- as blades of that arrangement are found to most effectively catch the earth and exert. the greatest drivin force. Attached to the drive wheel M is t e main gear N, which is driven by the pinion n on the engine shaft R. It may be stated here that the motor K may in It is, however, convenient and less trouble-. some to employ an engine of the internal explosion kind using gasolene, as there are many such in the market at present.

It is occasionally necessary and desirable that this invention should be moved about more or less, forexample, in the farm imengaging the pinion n and suitably supported by the suitable bearing Q. Engage ing the gear P is a pinion R that is turned by the handcrank 1'. When the carriage is moved "by the handcrank, the motor is, of course, released by disengaging the clutch 0.

Further considering the drawings, the plowshare S has avertical standard 8 movable up and down in a uide-block T at tached to the main frame Upon one side of the standard .9 is a toothed rack and a pinion U carried in the bearings V, andoperated by the gear wheel u, on the same shaft, turned by the pinion w and handcrank W. The plowbeam X. is connected with the-front post C of the main frame by means ofthe clevis Y. It will be noted in the drawings that the guide block T mentioned as occupied b the standard of .the plow, may be move along the frame A of the grip of the blades of the driving wheel in the earth. In practice the driving wheel runs in the furrow, and, the platform B is arranged to be level when about six inches of the driving wheel is sunk in the furrow. In other words, when this invention rests upon even ground, that side or end of the platform nearest the driving wheel is about six inches higher than the outer end at which the supporting wheel Z'is located. In op eration, the guiding wheel H and the platform-supporting wheel Z moveevenly upon unplowed ground and the vibration of the whole structure is materially'reduced. The plowshare may be raised or lowered by. means .of handcrankW, and in order to in- .sure the turning of the platform with the main frame and without vibration or undue strain, a removable rod 3 is attached to the vertical front post C, and to the free end 4 of the platform, carried by wheel Z. When this invention is housed the rod'3 is removed in order that room may be afforded to place some other machine or implements near the main frame Aof this invention. Attention is also called to the fact that b placing the motor to the side of the main f i'ame, and in locating the o erators seat near it, the motor is not su jected to shocks during the plowing movement, and the comfort ofthe operator is also enhanced.

It will be noted that the gear P and the pinion p, the bearing Q, and the pinion R with its handcrank 9", are'all borne by the plate 5, and that the plate by means of the handscrew 6 may be moved between suitable guide bars 7 either toward or from pinion n on engine shaft is. The purpose of that arrangement is tofree the hand-operated devices from engagement with pinion n, when the motor is used. When the guide-block T and its stated attachments are moved along the frame Ato a desired position, it is secured by bolts 12 passed through the holes d shown in Fig. 3.

structed to secure said mechanism ;at diiferent. places upon the frame in orderl'to allow for plow beams of different lengths.

2. In a motor low, the combination with a main frame, 0 a guiding wheel arranged at the front of the main frame, a driving wheel supported by the main frame, a plow connected with the main frame adjacent to the driving wheel, the said plow having a vertical standard, means movable length-' wise on the main frame and constructed to move the said standard-up and down and to guide the same a platform arranged at right angles with the main frame,,a motor arranged upon the platform at one side of the driving wheel, means constructed to connect the motor and the driving wheel, a Wheel arranged to support the outer end of the platform, and means located near the motor on said platform and constructed to operate the. guide wheel.

3. In a motor plow, the combination with a main frame, of a guiding wheel arranged. at the front of the main frame, a driving wheel supported by the main frame, a plow connected with the main frame and arranged in advan ce of the driving wheel, the said plow having a vertical standard, means movable lengthwise on the main frame and constructed to move the said standard up and down and to guide the same, a platform arranged at right angles with the main frame, a motor arranged upon the platform at one side of the driving wheel, means constructed to connect the motor and the driving wheel, a wheel arranged to support the outer end of the platform, and means located near the motor on said platform and constructed to operate the guide wheel.
